Hi Group,

I'm facing a problem advertising a default route into RIP using the "ip
default-network" command. My setup as follows:

R1(s0/0/1)--------
131.108.99.0/24--------(s0/2)R3(s0/3)--------161.44.192.0/24--------(s0/0/1)R2

R1:
!
interface Serial0/0/1
 ip address 131.108.99.1 255.255.255.0
 clockrate 125000
!
router rip
 version 2
 network 131.108.0.0
 no auto-summary
!
ip classless
!

R2:
!
interface Loopback0
 ip address 198.10.1.1 255.255.255.0
!
interface Serial0/0/1
 ip address 161.44.192.2 255.255.255.0
 clockrate 125000
!
ip classless
!
R3:
!
interface Serial0/2
 ip address 131.108.99.3 255.255.255.0
!
interface Serial0/3
 ip address 161.44.192.3 255.255.255.0
!
router rip
 version 2
 network 131.108.0.0
 no auto-summary
!
ip default-network 198.10.1.0
ip route 198.10.1.0 255.255.255.0 161.44.192.2
!
ip classless
!

R3#sh ip ro
Gateway of last resort is 161.44.192.2 to network 198.10.1.0

     161.44.0.0/24 is subnetted, 1 subnets
C 161.44.192.0 is directly connected, Serial0/3
     131.108.0.0/24 is subnetted, 1 subnets
C 131.108.99.0 is directly connected, Serial0/2
S* 198.10.1.0/24 [1/0] via 161.44.192.2

R3#deb ip rip
RIP protocol debugging is on
*Mar 1 07:10:47.535: RIP: sending v2 update to 224.0.0.9 via Serial0/2 (
131.108.99.3)
*Mar 1 07:10:47.535: RIP: build update entries - suppressing null update

R1#sh ip ro
Gateway of last resort is not set

     131.108.0.0/24 is subnetted, 1 subnets
C 131.108.99.0 is directly connected, Serial0/0/1

I'm expecting R3 to advertise a default route into RIP as a result of the
"ip default-network" command. However it doesn't. Can anyone tell me what am
I missing in my configuration?

Thank you.

BR,
Emil
